Cooling Holes Inspection / Cooling Hole Measurement and Verification

 The 700-Series VisionGauge® Digital Optical Comparator is the Perfect Solution for EDM- and LASER-Drilled Holes and Slots Inspection and Measurement

The VisionGauge® Digital Optical Comparator is widely used by manufacturers across a broad range of industries (including aerospace and power generation) to inspect and measure EDM- and LASER-drilled cooling holes and slots:

  • Automatically verify hole presence & accurately measure hole location
  • Supports both round and shaped holes
  • 5 axes of motion (X, Y, Z, Rotary, Tilt) to properly view parts from all sides & angles
  • Quickly, easily, and accurately inspect 100% of the holes on your parts
  • Robust shop floor design
  • Can output the hole offsets which can be used to modify EDM drilling programs
  • Mounting system allows your parts to go directly from the EDM drilling machine to the inspection and measurement system without re-fixturing (quick & easy and also minimizes stack-up error, etc…)
  • The system can be supplied with the same working envelope as your EDM drill. If you can drill it, we can check it!
  • Holes can be checked either one at a time, looking straight down each hole’s nominal axis (ideal for coated parts, to minimize errors due to coating thickness variations) or multiple holes can be checked at once, viewing them at an angle (which is even faster and well suited for uncoated parts or parts with a uniform coating thickness)
  • The system has an extended depth of field, so that everything is perfectly in focus regardless of the part’s geometry (even in areas of very high curvature) as well as a very long working distance (so that there is lots of clearance between the part and the entire optical system to comfortably accommodate large and unusually-shaped parts)
  • Extremely powerful “adaptive” feature-detection software tools are able to accurately find and locate EDM-drilled holes on different surfaces, with different reflectivity, at different viewing angles, etc…
  • Specialized software tools are especially well suited to deal with burrs and splatter
  • Automatically create reports and collect measurements, statistics, images and other data for complete documentation
  • Fast and intuitive “operator review” mode allows the operator to quickly revisit out-of-tolerance areas, etc…
  • The ideal system for inspection and measurement of cooling holes on aircraft engine and IGT (Industrial Gas Turbine) components (blades, vanes, heat shields, shrouds, etc.). Parts can be either (ceramic) coated or uncoated.

Turbine Blade Fir Tree Root Form Inspection and Measurement

The Perfect Solution For the Inspection and Measurement of Turbine Blade Fir Tree Root Forms 

There are many reasons why the VisionGauge® Digital Optical Comparator is widely used by manufacturers in the aerospace and power generation industries to perform turbine blade fir tree root forms inspection and measurement:

  • Automatically compare turbine blade fir tree root forms against their CAD data (no more overlays!).
  • The system can completely automatically inspect and measure turbine blade fir tree root forms with its proprietary CAD Auto-Align and CAD Auto-Pass/Fail tools (Patents Pending).
  • Demonstrated accuracy down to +/-0.0001″ in real-world applications, directly on the shop floor!
  • The system supports both uniform and variable tolerances. You can apply tighter tolerances on pressure faces and looser tolerances elsewhere.
  • Eliminate operator subjectivity!
  • Much faster than traditional approaches.
  • Automatically collect measurements, statistics, images and other data for complete documentation.
  • The system is not limited to the camera’s field-of-view; It can compare a part to its CAD data across the entire stage travel. So even large parts can be inspected at high magnification.
  • With its extended optical depth-of-field and Auto-Focus tool, the system is perfectly suited to deal with the challenges of turbine blade fir tree root form inspection.
  • Automatically measure and display deviations from nominal and quickly identify out-of-tolerance areas.

Turbine Disk Inspection

The Perfect Solution For Turbine Disk Inspection

There are many reasons why the VisionGauge® Digital Optical Comparator is widely used by manufacturers in the aerospace and power generation industries for the inspection of turbine disks:

  • Automatically compare turbine disk fir trees directly against their CAD data (no more overlays!).
  • With its proprietary CAD Auto-Align™ and CAD Auto-Pass/Fail™ tools (Patents Pending), the system can inspect turbine disks completely automatically!
  • Demonstrated accuracy down to +/-0.0001″ in real-world applications, directly on the shop floor!
  • The system supports both uniform and variable tolerances. You can apply tighter tolerances on pressure faces and looser tolerances elsewhere. Tolerances can be made to vary gradually between different zones.
  • Also ideal for the inspection of blisks, EDM slots, and other aerospace engine components.
  • Eliminate operator subjectivity!
  • Much faster than traditional approaches.
  • Automatically collect measurements, statistics, images, and other data for complete documentation.
  • The system is not limited to the camera’s field-of-view; It can compare a part to its CAD data across the entire stage travel. So even large parts can be checked at high magnification.
  • With its extended optical depth-of-field and Auto-Focus tool, the system is perfectly suited to deal with the challenges of turbine disk inspection.
  • Automatically measure and display deviations from nominal and quickly identify out-of-tolerance areas.
